COIEBINED DISTRIBUTER AND TIMER DEVICE.

Specification of Letters Patent.

Patented July 13, 1909.

Application filed. Novemben 13, 1908. Serial No. 462,413.

Be it known that we, Tnnonon M. MUEL- LER, a subject of the Emperor of'Germany, and ALBERT JACOB, a citizen of the United States of America, residing at Dalton, in the county of Berkshire and State of Massachusetts, have invented new and ,useful Imrovements in Combined 'Distributer and imer Devices, of which the following is a specification.

, Our present invention relates to improvements in combined distributers and timers,

as used in electrical ignition systems for.

igniting the charge of internal combustion or vapor engines.

The object of the invention is to produce a device that is simple and reliable in construction and one that may be readily changed or converted into a simple distributer without reference to the timing feature; that is to say,when the device is to be used in connection with a magneto or non-vibratory coil alone, and not in connection with an of the make and break or vibratory type.

Referring to the drawings forming part of this application,--Figure 1 is a plan view of the distributor end of the device showing the binding 0st for receiving a high-tension terminal and also binding-posts to which the lead wires are connected to the various cylinders. Fig. 2 is a vertical sectional view on the line 22 of Fig. 1 clearly illustrating the internal construction of the device the parts being indicated at the moment that the distributor plate is passing one of the terminals and the resilient contact arms or fingers are in contact with the primary terminal, and Fig. 3 is a horizontal sectional view on the line 33 of Fig. 2 illustrating the radial arrangement of the resilient contact fin ers with relation to the driving shaft an the primary terminal.

In the drawings, a designates the shell or casing of the device which is preferably comjj' 'posed of some high insulating gia'rd rubber or pre material, as ared fiber, and in the are-located the various 1) that are cast in the base portion and terminate in the sparkoint d, which in practice is preferably nicke -plated. The spring-clips e for receiving the lead-wires to the terminals b in any suitable way, as riveting.

f designates a high tension terminal that terminals is cast in the center part of the baseportion c and bored out to receive a coil spring 9 for the pur ose of normally pressing outward the har ened ball h against the distributerplate h that is carried by the disk-shaped distributer block "5 of insulating material shown in plan view in Fig. 1. This plate is secured to the block i in any suitable manner, as by. means of the screw Figs. 1 and 2.

The of the tubular hub k that is secured to the hub ortion m by means of the pin it, the part being secured to the block 'b by means of the plate 0 and screw p.

g designates a ring that is secured to the casing 11 in any suitable manner, as by means of the dowel pins g which are cast in the cas-. ing and secured to the ring g by means of the pin (1 The bushing or sleeve 7' of insulating material is located in the ring g, the sleeve the threaded terminal s that carries at its inner end are arranged to pass'through the fork t and make contact therewith are secured on the hub portion m.

The fingers o and 'w normally are of greater width or distance apart than the opening in the fork t whereby when these fingers engage the fork a good electrical contact is made, and it will be observed that the fingers'o and w are concavo convex or U-shaped in end elevation, asshown in dotted lines in Fig. 2.

cc designates aplate that is secured to the ring q in any suitable manner, as by means of a slot and screw connection (not shown) whereby the position of the fingers o and w may be so arranged'as to enga e or leave .the fork t at the same time that t e distributor plate It is passing one of the points d of the The plate a; is provided with a bushing or bearing surface 'y for a connecting shaft that is inserted in the bushin for driving the fiIlf gers o and w and the bloc i which carries the distributor-plate h.

' It has not been considered necessary to show the variouselectrical connections and circuits in which the distributor and timer device are employed, but it maybe stated that the contact fingers 42 and to pass through and through shown in distributer-block i is driven by means the contact fork t passes. .The resilient contact fingers o and w, WhlCll or leave the fork t, which is in the primary circuit, at the same time that the distributerplate It is adjacent the distributer point d that is in electrical contact with the termiof the device alone without employing thespring finger construction 1; and 'w, it is only necessary to remove the same and drive the distributer block '5 alone, it being understood that the terminal f is connected to the high tension side of a magneto or other source of high voltage current, and that the current will flow from the terminal f through the ball and plate to the terminals e in succession, as readily understood.

The timer contacts '0 and w and the contact forks t may, of course, be employed alone without using the distributer, by simply disconnecting the distributer block i from the drive-shaft by removing the pin it.

It will thus be seen that we have produced very simple and inexpensive device for car- -ying out the above described objects.

What we claim, is

1. A distribute! and timer device havin in combination, a base-plate, a termina mounted therein, a distributer rotatably mounted with relation to the terminal, the distributer bein provided with resilient fingers, anda fori gers engage during their rotation.

2. In a distributer and timer device, a rotatable member having spring or resilient l having sprin terminal with which said fingers secured thereto, said fingers being concavo convex in cross section, and a fork terminal with which the fingers engage dur- I ing their rotation.

. 3. A distributer and timer device having in combination, a casing or base-piece, a high tension terminal and distributer terminals mounted therein, a rotatable block rovided with conducting means in electrica contact with the high tension terminal, and a series of l resilient U-shaped fingers adapted for simultaneous rotation with the block, and a fork f terminal located in the path of the fingers, I described.

; 4. A distributer and timer device comprisl ing a casing, distributer terminals mounted therein, a rotatable block, a conducting plate carried thereby, terminal engaging the plate, a resilient U-shaped contact member adapted for rotation with said block, and a I fork terminal member located in the path of i the U-shaped contact member.

5. In a timer device, a rotatable member or resilient fingers secured thereto, said gers being concavo convex in I cross section, and a fork terminal with which I the fingers enga e durin their rotation. T EODU]? M. MUELLER.
